-- or, perhaps, Zombie Hard Drive.
I've got a Western Digital external hard drive: WD5000E035-00, to be precise. I use Windows XP on a Dell with a Pentium 4.
Overnight, the hard drive stopped working.
The little green light on the power cord keeps blinking. I replaced the USB cord with one that I know works, into a USB outlet that I know works. I plugged the hard drive into my wife's computer.
And yet neither the Device Manager, nor My Computer, recognizes that I even have a hard drive anymore.
